A tumor sample sampling device

Abstract

The invention relates to a tumor sample sampling device, comprising a sampling syringe, a sampling knife rod, a sampling U-shaped knife, a sampling needle and a piston ring; Connecting threads; the sampling knife rod is installed on the sampling syringe along the longitudinal direction of the syringe, and the same direction end of the sampling knife rod and the closed end of the sampling syringe is fixedly connected with a threaded connecting column; the sampling U-shaped knife and the threaded connecting column are detachable Threaded connection; the sampling needle is a cylindrical shape with a closed front end and a cutout on the side end. The sampling needle is set on the outside of the sampling U-shaped knife and is connected with a detachable screw thread at the closed end of the sampling syringe; the piston ring is set on the The sampling knife rod is in sealing and sliding connection with the inner side of the sampling syringe. The invention is simple and convenient to use, high in sampling efficiency, short in operation time, safe and reliable, and reduces the work difficulty of medical staff; and the sampling U-shaped knife and sampling needle can be made into disposable products, which are safer to use.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a tumor sample sampling device. Background technique [0002] Tumor refers to the new organism formed by the proliferation of local tissue cells under the action of various tumorigenic factors, because this new organism is mostly in the form of space-occupying blocky protrusions, also known as neoplasm, regardless of its cell shape and tissue structure. In general, they are different from the normal tissue from which they originated. Tumors are divided into benign and malignant. Not all tumors are cancers. Only malignant tumors can be called cancers. Cells from the diseased site are sampled for analysis, thus requiring specialized tumor sampling devices. [0003] In the course of treatment in the oncology department, diseased tissue needs to be removed from the patient's body by cutting, clamping or puncturing for pathological examination. This kind of examination is cal...

Problems solved by technology

[0004] However, in the existing technology, there are inconvenient operation and difficult cutting in puncture sampling, troublesome operation, time-consuming and laborious operation when performing tumor biopsy cutting on patients, which increases the work difficulty of medical staff, and the samples taken out after puncture not only include Tumor cells, including part of the epidermis and muscle tissue, have a certain impact on the purity of the sample, and the existing sampling equipment is used multiple times, there is a risk of mutual infection between users
